最近实验室的学弟学妹们要展示自己的静态网站作业，想着自己阿里云上还有一台服务器，就准备用docke 给他们做一个展示。参考了一部分dockerfile但是仍然不太好 
列出Dockerfile

FROM alpine:latest
MAINTAINER becivells <becivells@gmail.com> 
RUN apk add --update openssh
RUN apk add nginx
RUN ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
RUN sed -i "s/UsePrivilegeSeparation.*/UsePrivilegeSeparation no/g" /etc/ssh/sshd_config && sed -i "s/UsePAM.*/UsePAM no/g" /etc/ssh/sshd_config && sed -i "s/PermitRootLogin.*/PermitRootLogin yes/g" /etc/ssh/sshd_config && sed -i "s/#AuthorizedKeysFile/AuthorizedKeysFile/g" /etc/ssh/sshd_config
EXPOSE 80
EXPOSE 22
CMD ["nginx", "-g", "daemon off;"]
CMD ["/usr/sbin/sshd","-D"]

建立Docker 镜像dockerfile要和执行命令的在一个路径下

docker build -t alpine:nginx_ssh .

alpine Linux 确实小。而且管理方便。但是软件源少，也缺少一些管理命令需要手动安装

apk --update add 软件名#更新并且下载软件
例如 apk --update add openssh #我参照官网上配置ssh,结果ssh死活不能用
apk search 软件名 #搜索软件

觉得其他的和其他linux 基本上都一样  建立以后运行  docker run -i -t -p 80:80 -p 2333:22 alpine:nginx_ssh sh  下一条只做参考

docker run -i -t -p 80:80 -p 2333:22 -v /docker/alpine/nginx:/var/lib/nginx/html alpine:nginx_ssh sh

2016-11-5改进了一下，用证书登录，当然也可以用密码登陆

运行


docker run -d -p 80:80 -p 23333:22 -v /主机目录/:/var/www  nginx

可以拉取docker pull becivells/nginxssh



可以写个脚本批量开启参考https://hub.docker.com/r/danielguerra/alpine-sshd/~/dockerfile/
